Briefly described, my invention, as'sh'own.

in the (Irawiiigs;: cam uses hollow members of sheet metal, preferably,though not necessarily, copper, that, respectively engage the glass onthe outer side, and the inner side, the outer member for conveniencebeing hereinafter termed the sash, and the inner member being termed thegutter,

and which members are of identical con struction on all four sides ofthe glass, namely sill, side j'ambs and head amb.

Referring now in detail to what appears in Figs. 1 and 2, the sill 10,is, as is common,

of wood, and upon its top set back from the front is a stop 11 of wood,and the side and head jambs have corresponding construction. The sillhas its outer face and top covered with a copper covering 12, which atthe rear has a vertical flange that covers the face'of the stop 11, sothat all thereby protected.

The sash comprises a base 13 with vertical flanges l4spaced asubstantial distance one in advance of the other, whose edges engage thesill or jamb and an inwardly extending inclined or oblique member 15,

wood surfaces that require protection are that reaches from the outerflange 14, to the glass 16 which it engages by a lip 17, and

by. or is inelud'edf within the terms by an inwardly inclined wooclsorew 1'8, t-he; sash, by indirect pressure broughtto'bear upon theoblique niemberj l 5, is 'madef to exert- 15 ositive: yet resilientpressure" against the outer-sideof the glass toclamp it against thegutter on the inside: The oblique meniber '1-5'isgiven' the contour o'fa' niol'ding t'o enhance its appearance and to ender-n: elastic betweenits} front; flange 14 and 1 its glassaengaging lip;

Holes 19 are provided at intervalsthrough each flange 14, forventilation, and in the case of the sill, for drainage, and these holesare-staggered so-that no dust canpass directly through the holes in bothflanges, but it is trapped between them, for there can be no directcurrents of air through the base, which, with the diminution of theforce of the flowing air, by reason" of its'circuitous course, hindersthe passage of dust.

The arched form of the base enables the 1' of, and there has aflange 22at right angles 7 that lies parallel with the top portion 21 and reachesto the face of the stop, or the copper cover thereof, so that, as thegutter is secured by screws 23 to the stop, there are two parallelspaced portions at right angles to the glass that resist the inwardpressure dust are diminished and changed.

these twoparallel portions are holes 24 at intervals for ventilation anddrainage (in the case of the still), and as there are these two portionsthe holes are staggered, as "in the case of the sash base, and thus theforce and direction of air currents, that would carry The gutter has atits rear edge a hollow bead 25 that forms a barrier to water tending topass'to the top of the stop that has no protecting covering.

The holes in the top or outer member 21 have an inturned flange 26, thatso directs water from the gutter that it is kept from flowing along theunderside of the portion 21 to the 'joint at the top of the stop.

In;the form of my invention shownin Fig. 3, the sash 27 is the sameasinFigs. 1 and 2, but the gutter and sill cover are different, the sillcover 28 not reaching to the front of the stop 29, but the latter iscovered by a flangeBO from the gutter 31, and the latter has asub-gutter 32, formed by vertical flanges and a base. I

I claim:

1. lVindow construction having, a glassengaging hollow sash of sheetmetal provided with a base extended a substantial distance in thedirection towards the glass, and having an obliquely extending portionreaching from the outer side of the base towards the glass, saidobliquely extending portion and said base being joined and the basebeing plane and having at its outer and inner edgesvertical flanges,.anddownwardly and inwardly extending screws passi'ngthrough alining holesin said obliquely extending portion and saidbase, the screws havingheads to engage and exert clamping pressure against sald obllquelyextending portion, the holes in the base being situated and an opposingmember ofsheet metal that has a portion extending horizontally inwardfrom the glass, a supporting surface over which such portion extends andupon which it bears, said horizontally extending portion terminating ina hollow bead that extends transversely of the window, and said sheetmetal member having next the glass a vertical glass engaging portionthat extends downwardly from said horizontally extending portion, thelatterIb-etween said bead and said vertically extending portion beingplane, and said sheet metal memberhaving ahorizontally extending portionthat terminates in a free edge and a vertical surface against which suchfree edge bears, whereby inward pressure on the glass is transmittedthrough said last named horizontally extending portion to the verticalsurface with which its free edge contacts.

In testimony whereof I hereunto aflix signature.
